Some people can remember card order of the deck of 52 cards.
They use story as way to remember. A Memory Palace method.
"So, as I walked inside the house I saw a book..."

Our ancestors used it too, to store the knowledge.
Maybe not the memory palace method, but still.
You can use it to remember things too. For example things to do.
And other things.
Try with something simple, then increase the number of things to remember.
